这项工作分析了西班牙城镇使用的分离收集系统，居民在5000至50，000之间。该研究通过分级率、容器质量率和分离率等指标来考察系统及其效率。所获得的结果与早些时候进行的一项适用于人口超过50 000的城镇的类似研究的结果进行了比较。可以得出的结论是，西班牙最广泛实施的系统涉及从路边垃圾箱收集混合废物，并从落客点拾取纸/纸板、玻璃和轻质包装。调查结果表明，最好的系统是挨家挨户收集混合废物、有机材料和多产品废物以及从投放点收集玻璃的系统。指标分离率使得有可能建立贝塔回归模型，以分析以下逻辑变量的影响：每个点的居民（人/点）、时间（年）和采集频率（频率）。从这些模型可以看出，人/pt对所有分数都有负面影响，而频率和年份对纸张有正面影响。(C)2012爱思唯尔有限公司保留所有权利。
This work analyses the separate collection systems used in Spanish towns with between 5000 and 50,000 inhabitants. The study looks at the systems and their efficiency by means of the indicators fractioning rate, quality in container rate and separation rate. The results obtained are compared with those from a similar study conducted earlier that was applied to towns and cities with populations over 50,000. It can be concluded that the most widely implemented system in Spain involves the collection of mixed waste from kerbside bins and picking up paper/cardboard, glass and lightweight packaging from drop-off points. Findings show that the best system is the one that collects mixed waste, organic material and multiproduct waste door-to-door, and glass from drop-off points. The indicator separation rate made it possible to establish beta regression models to analyse the influence of the following logistic variables: inhabitants per point (people/pt), time (years) and frequency of collection (freq). From these models it can be seen that people/pt has a negative effect on all the fractions, while freq and years have a positive effect in the case of paper. (C) 2012 Elsevier Ltd.
